IMPROVEMENT l-N HEATING APPARATUS.

Specification forming part of Letters Patent No. 209,650, dated Novembers, 1878 application filed September 5, 1878.

To all whom it may concern:

Be it known that I, ABNER BURBANK, of the city of Rochester, county ofMonroe, and State of New York, have invented a certain new and usefulImprovement in Heating Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanyin g drawings, in which- Figure 1 is asectional side elevation of the apparatus arranged as an oil-stove.Figs. 2 and 3 are detail views.

My improvement relates to apparatus for burning kerosene-oil without awick, whereby much better combustion is attained and a more intense heatis produced than in tip paratus where wicks are employed.

The invention consists in the construction and arrangement of parts,hereinafter more fully described.

In the drawings, A indicates an inverted fountain containing the oil,the neck of which rests within a vessel B, from tlied'iottom of which afeed pipe j, extends to and opens into an oil-receptacle, O, to the topof which is attached an ordinary wick-burner, D. The fountain A has avalve,-a, with a stem, a, which, when it rests in vessel B, strikes. thebottom thereof and allows the oil to flow out into said vessel, actingin this respect similarly'to the and this is stopped by a Cork, 0; or,if desired,

a safety-valve may be employed. In the top of the boiler is also aremovable cap, d, by which the interior may be reached.

H is an open-topped drum or cylindermounted on a level, or nearly so,with the boiler. From the bottom or through the side proceeds a tube, f,having a funnel-shaped outer end, f, which stands toward the boiler.

g is a pipe similar to b, which extends from the receiver 0 up to andjust beneath said pipe b. The ends of both these pipes are provided withsmall orifices, and that of I), through which the steam escapes, formsan injector, which, blowing across and in close contact with that of g,tends to produce a vacuum in pipe 9, and thereby draws the oil upthrough said pipe g and discharges it with the steam into theopen-mouthed pipe or tube f, and thence into the cylinder H. The pipe 9is provided with a cook, or is otherwise arranged to graduate the flowof oil through the same, and the pipe I) may-also be provided with acock to regulate the steam.

The operation is as follows: The burner D being lighted, steam isquickly generated in the boiler G, and from thence is injected throughpipe 1), drawing the oil up through pipe 9, and forcing it through tubefinto the cylinder H, as before described. A large quantityof theoutside air is also drawn into the cylinder by the force of theinjection. Fire is now communicated to the atomized spray which entersthe cylinder, and, the flame being confined therein, an intense heat isat once produced, greatly exceeding that which can be produced by.wick-burners. The decomposed gases of the steam, as well as the greatvolume of outside air which enters, abundantly supplies the combustionso that the oil is all burned.

The cylinder is essential to concentrate and hold the flame, for if notused the spray would be diffused and burn over a great surface. So faras the action of the cylinder and tube is concerned, a jet of impelledair or other fluid might be used with a similar efl'ect as steam, sinceit would draw up the oil, atomize it, and drive it into the cylinder tobe burned.

h. h are small wire-cloth screens, of circular or other form, at theends of the pipes 12 g, which enter the oil-receptacle and boiler. Themesh of these screens is smaller than the orifices at the outer ends ofsaid pipes, so that they will strain the oil and steam, preventing theentrance of particles that might obstruct said orifices. The pipe 11passes up through the boiler to the top directly under the cap (I, by

' which it comes above the water-line, and also presents the screen inposition to be reached. The pipe I) and screen h in the chamber G alsoserve a highly-important function in preventing priming or the carryingover bodily particles of water from the boiler, which would materiallyinterfere with the operation of the apparatus.

The apparatus above described is adapted to many diiferent purposes,such as oil-stoves for domestic use, t-inmens furnaces, jewelers andmechanics uses, &c. The heat is so quickly produced and is so intense asto render it of great service where oil cannot now be used.

It is not at all necessary that the pipe 9 should enter the receptacle0, as shown in the drawing. It may enter or connect with a separatereceptacle with the same result.

Having thus described my invention, I claim- 1. A portable heatingapparatus for burnin g hydrocarbons, in which are combined a cylinder,H, having tube f, the receptacle 0, the chimney or heat-conductor E, theseparate boiler G, resting on the chimney, with a pipe, I), proceedingfrom the boiler, and a pipe, g, proceeding from an oil-fount, the twopipes uniting in front of the tube f, for conveying oil and steam andinjecting the oil through said tube to the interior of the cylinder H,substantially as shown and described, and for the purpose specified.

2. In a portable heating-apparatus, the combination of the oil-fount O,chimney or heatconductor E, and separate boiler G, provided with thepipes 11 g, constituting an injector, the whole forming an attachmentcapable of raising the oil and injecting the same through pipe f intothe cylinder H, substantially as shown and described, and for thepurpose specified.

3. In a portableheating apparatus such as described, the combination,with pipes b g, of the perforated screens h h, inclosing the inductionends of said pipes, and having their perforations as small as or smallerthan the discharge-orifices of said pipes, as herein shown anddescribed.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

ABNER BURBANK.
